I've had issues on my 12th filament block where the servo (from dfh kit) reaches the proper gripping position, but always slides back. Instead of changing the servo, I decided to modify the piece to add a small bump that prevents the servo from sliding back, but still allows it to move past it in both directions when commanded.
